How do you calculate arc length without knowing the radius?

To calculate the arc length without knowing the radius, you must know the central angle and either the area of the sector, the length of the chord, or the area of the entire circle from which the sector is a part of. If you know one of the former two, check the above sections for the appropriate formula to use.

What is the formula for arc length of a circle?

The formula for the arc length of a circle is: Arc length = θ 360 o. 2 π r 10 = θ 360 o. 2 r 5 = θ 360 o. R (1) Likewise, we are also given the area of the sector of the circle and the formula for the area of the sector is given as: Area of the sector = θ 360 o. π r 2 60 π = θ 360 o. π r 2 60 = θ 360 o. r 2 (2)
